Staple Fiber Nonwoven Geotextile
Staple fiber needle-punched nonwoven geotextile, a high-performance permeable filtration geosynthetic material.
Short fiber needle-punched nonwoven geotextile is a high-performance permeable and filtration geosynthetic material, made from high-molecular fibers such as PET and PP. This product has a loose structure, uniform three-dimensional pore distribution, and excellent filtration and drainage performance, making it the most widely used filter layer and protective layer material in geotechnical engineering. Our products can be manufactured according to GB/T, ASTM, ISO, and other standards, and all raw materials are pure new resin.
Production Process: High-quality geotextiles are made from polymer fibers through physical web formation, needle punching, and heat setting processes. The production process varies slightly depending on the raw materials, as their properties differ.
Quality Control: The entire production process is monitored by automation. Strict factory inspections are conducted in accordance with standards, to ensure that the dimensions, appearance, and key properties. We have very clear standards for controlling appearance defects, distinguishing between superior and qualified products.
After-sales Service: We have over one million square meters of construction experience, and our team can provide on-site construction services. We also offer remote technical guidance to assist with welding and construction.
Advantages
- Excellent Filtration and Reverse Filtration Functions: the equivalent aperture O₉₀ is controlled within a precise range of 0.07～0.20mm.
- Reliable drainage capacity: Vertical permeability coefficient can reach K×(10⁻¹～10⁻³) cm/s.
- Superior Protective Performance: mass range of 100g/m² to 800g/m², can cover nominal strength from 3kN/m to 40kN/m.
- Good Durability and Environmental Adaptability

- Landfill Seepage Control System:
- As the upper protective layer and lower cushion layer of HDPE geomembrane, it buffers the impact of crushed stone and compaction machinery on the membrane, while simultaneously draining leachate and groundwater. A nominal strength of 15kN/m or higher is recommended.
- Railway and Highway Subgrade Engineering:
- Layed between soft soil foundations and fill layers, it serves a triple function of isolation, reinforcement, and drainage, preventing subgrade mud pumping. Typical applications: high-speed railway subgrade cushion layer, high-fill embankment reinforcement layer.
- Hydraulic Embankment and Bank Protection Engineering:
- As a filter layer between riprap slope protection and soil, it prevents soil loss due to wave erosion while maintaining unobstructed slope drainage. Typical examples: concealed works of important Yangtze River embankments, lining of the South-to-North Water Diversion Project's central route canals.
- Tunnel and Underground Engineering:
- Layed between initial support and waterproofing membrane, it protects the waterproofing membrane from punctures by sharp particles of shotcrete, while simultaneously draining seepage from the surrounding rock.
- Agricultural and ecological engineering:
- Reverse filtration and drainage layers used in reservoirs, irrigation canals, and constructed wetlands, as well as water-retaining and filtration layers for rooftop greening and slope greening.
